Be itknown that I, HAM-'CHRISTIAN LUCK, a citizenof the United States,and a resident of Telluride, in the county lof San Miguel and State ofColorado, have inventedra new and ImprovedAir-Brake Appliance, of whichthe following is a full, clear, and eX'ac't description.

The invention vrelates to fluid pressure brakes for railroad-trains;:and its object is to provide a new and improved air-brake -appliancearranged to automatically set the brakes in the train in case any one ofthe cars in the train becomes derailed.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is an under side view of a car provided With the improvement.Fig. 2 is a perspective view of the improvement. Fig. 3 is a transversesection of the same, and Fig. 4 is a longitudinal sectional elevation ofthe operating-fork.

The train-pipe A of a iiuid-pressure brake of the Westinghouse or yothertype and secured to the under side of the car-body B of a car isprovided with a branch pipe C, the depending end of which is providedwith a valve-seat D, of rubber or other suitable material and normallyclosed by a valve in the form of a lever E, extending longitudinally andfulcrumed at E on a bracket F, secured to the under side of the car-bodyB.

The valve-lever E rests on a transverse bar Gr, carried by a bracket Fsecured to the under side of the car-body, and this bar G is locateddirectly below the valve-seat D and is connected by bolts H with a barII, carrying a nut D', screwing on the terminal of the branch pipe C andserving to hold the valveseat D in place, it bein understood that by thearrangement descri ed the 'valve-lever E is firmly held in engagementwith the seat D to close the end of the branch pipe C, and at the sametime the valve-lever E can be swung to one side, so as to open thebranch pipe C for the escape of air from the train-pipe A with a view-to automatically set the brakes in the usual manner.

The free end of the valve-leverEis provided With a vertical arm E?,extending betweenf the members I and I2 of a fork I, attached to a rodI3, secured to the bolster of th'e cartruck J, so that when thelatterleaves the rails and the. car-truck assumes an angular position relativeto the car-body B then the fork I on account of beinga permanent fixtureof the truck moves with the latter, and consequently imparts a sidewiseswin-gingmotion to the valve-lever E to move 'the latt'er from under thevalve seat D to open the branch pipe C for the escape of air to actuatethe air-brakemechanism in the usual manner with a view to setting thebrakes to bring the train to a stop.

The branch pipe C is provided With a cutout valve K, which is normallyopen, but is adapted to be closed by an operator after the train hascome to a standstill, so that the airbrake mechanism in the train can bemanipulated in the usual manner and while the valve-lever E is off theseat D. A

The members I and I2 of the fork I are adjustably secured in the bar I3by a set-screw I4 to bring the members the desired distance apart with aview to allow the truck to readl ily pass around sharp curves withoutthe corresponding member I or I2 striking the bar E2. Thus the car canreadily pass around sharp curves without danger of the air-brakes beingautomatically applied by the device above described, it being understoodthat the angle of position of the car-truck relative to the carbody mustbe more than that assumed by a train going around a sharp curve for thedevice to automatically set the brakes asabove described.

From the foregoing it will be seen that only in case of derailment of atruck and its consequent angular position relative to the carbodyBcauses a quick ap lication ofthe brakes by means of the air-bra esystem, so that the train is automatically brought to a standstillwithin a comparatively short time after the derailment has takeny place,and consequently serious damage to'the train and to the road-bed isentirely prevented.

The device is very simple and durable in construction, is not liable toget easily out of order, and can be readily applied to cars as nowequipped with air-brake systems. It is understood that each car isprovided with two devices described, one for each truck, so that wheneither the front or the rear truck leaves the rails the brakes areapplied to bring the train to a standstill.

IOO

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. An air-brake appliance for automatically settingthe brakes on the derailment of a car in the train, comprising a forkiixed on the car5truck and having its members arranged in a horizontalplane, a branch pipe connected with the train-pipe, and a valve in theform of a lever fulcrumed on the car-body and normally closing the endof said branch pipe, the free end of said lever extending between themembers of the said fork whereby the rotation of the truck upon thecar-body beyond a predetermined angle may operate the lever to open thevalve.

2. An air-brake appliance for automatically setting the brakes on thederailment of a car in the train, comprising a fork iiXed on lopen thevalve, and a manuallycontrolled cut-out valve on the said branch-pipe.

In testimony whereof I have signed my name to this specification 1n thepresence of two subscribing witnesses.

HANS CHRISTIAN LUCK.
